Shared Blackboard variables are not synchronized when the Behavior Graph is loaded via Addressables using the Existing Build Play Mode Script

How to reproduce:

1. Open the attached “IN-145316_Behavior_Addressables” project
2. Open the “Test Addressables Scene”
3. Enable “Subgraph” Shared property in the “Blackboard” window
4. Set the “Play Mode Script” to “Use Existing Build” in the “Addressables Groups” window
5. Enter the Play mode
6. Press “A” multiple times
7. Observe the Console

Actual result: After a click the “Result” remains the same
Expected result: After every click the “Result” changes

Reproducible with: 1.0.13 (6000.0.32f1), 1.0.16 (6000.0.32f1, 6000.6.0a7)
Could not test with: 1.0.12 (6000.0.32f1) (missing parts in the graph)

Reproducible on: Windows 11

Notes:

• Reproducible with Addressables package versions 2.2.2 (6000.0.32f1), 3.1.0 (6000.0.32f1, 6000.6.0a7)
• Only reproducible when Existing Build is used as a Play Mode Script with Blackboard’s variable set to “Shared”
